CHARLES T. FULLER, OF OLEAN, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 759,689, dated May 10, 1904. Application filed February 17, 1904:, Serial No. 194,057. (No model.)

To all whom it may concern:

Be it known that I CHARLES T. FULLER, a citizen of the United States, residing at Olean, in the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in Extensible Burner Attachments and Shade-Supports; and 1 do declare the following to be a full, clear, and exact description of theinvention, such will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in gas-burners; and the object of the invention is to produce a device of this character whereby the tubes may be adjusted to various pressures of gas by raising the tube or extending the same, having the effect of decreasing the pressure upon the mantle and by shortening the length of the burnertubes increasing the pressure.

My invention consists, furthenin various details of construction and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

1 illustrate my invention in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and inwhich- Figure 1 is a side elevation of the burner, having my extensible tube attachments and bracket applied thereto. Fig. 2 is an enlarged sectional View through one of the tubes, showing the manner of holding the same in an adjusted position. and also the bracket for supporting the globe. Fig. 3 is a detail view of the bracket member detached, and Fig. i is a cross-sectional View through the clamping end of the extensible tube.

Reference now being had to the details of the drawings by letter, A designates a service-pipe or bracket-fixture having a suitable valve A therein and of ordinary construction, which may be provided with a threaded connecting-pipe a, and mounted upon and communicating with the pipe a is a turningwith a suitable mantle adapted to be covered by a globe F. The burner-tubes are provided with suitable valves D and apertures (Z for feeding oxygen for combustion purposes. flelescoping over each of the burners D is a tube H, which has a screen H at its-upper end, and the lower portion of each of said 5 tubes H has two integral arms H struck up or forming a portion of the tube and held parallel to each other and adapted to receive a threaded screw it, whereby said projecting portions may be drawn together for the pur- 7 pose of frictionally clamping the tube H to the burner D for holding the same in an adjusted position accordingly as it may be desired to utilize the burner with high or low pressure gas systems. the side of each tube H is a bracket-arm K, having a set-screw K and an aperture adapted to receive a mantle-supporting wire N.

M design ates a bracket-arm,one end of which is bent at an angle, as at M, and its other end is bifurcated, having two arms m, with an intermediate hook m, which is bent in the shape illustrated in the drawings and adapted to engage over the screw it to support said bracketarm, while the arms m are so disposed as to 5 contact with the burner D and hold the shank portion of said bracket-arm in a horizontal position to support the globe F.

From the foregoing it will be observed that by the provision of my improved apparatus 9 means is provided for taking ed the globe of the burner when either used as a drop-light or as a stationary light by simply unhooking the bracket-arms, which are carried by the extensible tubes, and by the provision of the means shown and described the space within the burner-tube and the extensible tube may be increased or decreased by raising or lowering the extensible tube accordingly as it may be desired to utilize the burner upon low Rising from the branching 55 Projecting from the 75 or high pressure systems, adapting the burner for use in various cities, where pressures vary.

While I have shown a certain detailed construction of apparatus embodying my invention, it will be understood that I may make changes in the same, if desired, without in any way departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a burner-tube, an extensible tube telescoping over said burnertube, clamping means for holding said extensible tube in an adjusted position, a globeholding bracket-arm supported by the latter and bearing against the burner-tube, as set forth. w

2. In combination with a burner-tube, a telescoping tube mounted thereon, lugs struck up from said teIescoping member, a screw passing through said lugs and adapted to clamp the telescoping tube in an adjusted position upon the burner-tube, and a globe-holding bracket supported by said screw and bearing against the burner-tube, as set forth.

3. In combination with a burner-tube, a telescoping tube mounted thereon, portions of said telescoping tube being outwardly bent forming lugs, a screw passing through threaded apertures in said lugs and adapted to frictionally draw the lugs together to hold the tube in an adjusted position, a mantle supported by the telescoping tube, a globe-holdingbracket having a bifurcated end, the arms of which are adapted to bear against the burner-tube, and a hook portion intermediate said arms and designed to engage over said screw, as set forth.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

CHARLES T. FULLER.
